I have been looking around and I have seen numbers translated to Klingon, but not months of the year. Does anyone know if the months Jan to Dec have been translated? My interest is becaus I have a text-based program I am working on and would like to add Klingon language to the dates as well as the time. Thank you.
There aren't any official transliterations of the names of the months (e.g., there's no *janyu'erI' or anything). Usually, months are simply rendered just as tera' jav wa' through tera' jav wa'maH cha' (Earth months 1 through 12).


Qu'vatlh! veH Suvvup SuvwI"a'.
"Month" is jar (jav is "six").
